Trait vapoursynth::plugins::FilterParameter

pub trait FilterParameter<'map, 'elem: 'map>: Sealed {
    type Argument: FilterArgument<'map, 'elem>;

    fn is_array() -> bool;
    fn is_optional() -> bool;
    fn get_from_map(map: &'map Map<'elem>, key: &str) -> Self;
}

An internal trait representing a filter parameter type (argument type + whether it’s an array or optional).

Required Associated Types

type Argument: FilterArgument<'map, 'elem>

The underlying argument type for this parameter type.

Required Methods

fn is_array() -> bool

Returns whether this parameter is an array.

fn is_optional() -> bool

Returns whether this parameter is optional.

fn get_from_map(map: &'map Map<'elem>, key: &str) -> Self

Retrieves this parameter from the given map.
